Patented Oct. 13, 1931 UNITED STATES PATENT OFFICE ARTHUR E. PAIGE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOB 10 JOHN WOOD MANUFACTURING COMPANY, OF GONSHOHOCKEN, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA HEAT nxcmnen APPARATUS Original application Med January 18, 1928, Serial No. 247,696. Divided and this application flled December 10, 1929. Serial No. 412,872.-

This is a division of my original application Serial No. 247,696 filed January 18, 1928, for Letters Patent of the United States for improvement in methods of heating and ventors, to heat the atmosphere local tothe radiator surface. The purpose and effect of my invention are to facilitate and augment the transfer of heat from the radiator surface to the adjacent atmosphere by more rapid displacement of the air at such surface than is possible by convection; and at a rate variable with the heat supplied As hereinafter described, my invention includes a means for facilitating and augmenting the transfer of heat from a fluid supplied to a radiator to the atmosphere adjacent to the radiator, by utilizing power from the heating fluid to operate a motor to forcibly circulate the air relatively to the radiator, by means of a rotary fan.

The typical heating system herein disclosed includes a gas burning water heater and means for maintaining a. forced circulation of water within the heating system, by an electrically controlled pump; the operation of the device being controlled by thermostatically operative means; and the forced circulation of air through the radiator is effected by a motor included in a bypass short-circuiting the radiator with which it is associated; so that the heating fluid is taken into the motor from the supply conduit leading from the heater to the radiator, and the exhaust from the motor is discharged into the return pipe leading from the radiator back to the heater. My invention includes the various novel ing a house heating system embodying my invention. v

F ig.'II is a vertical sectional view of one of the radiator structures shown in Fig. I, taken on the line II, II.

Fig. III is a plan sectional view of said structure, taken on the line III, III in Figs. I and II.

Fig. IV is a fragmentary sectional view of the fluid motor indicated in Figs. I and II.

Fig. V is a fragmentary sectional view of a modified form of fluid motor.

Referring to I; the house or other building, comprising rooms or other inclo- I sures 2 and 3, has, preferably in the'cellar 4 thereof, the heater 6 inclosing the burners 7 and 8 supplied with gas from the conduit 9 under control of the thermostatically operative valve in the casing 10. Said valve casing carries the tubular thermostatic element 11 extending within the water conduit 12 which is connected with the pipe 14 through which hot water is delivered from the cel-- lular heater units 16 which are supplied with cold water through the pipe 18. Said conduit 12 is connected by pipes 20 with radiator u'nits'21, from which the water is returned through pipes 23 to the pump 24 which is connected to said pipe 18 and arranged to be operated by the electric motor 25, under control of the. thermostatically operative switches 27, which are respectively local to the radiators 21 as indicated in Fig 1. Said pump is operated to circulate the water a through the system in the direction indicated form a cellular honeycomb of thin metalwalls and comprising separate passageways 35 for hot water or steam and 36 for atmospheric air. Said radiator includes the inlet port 38 and the outlet port 39 in communication with said plassageways 35 for the heating medium. T e outer casing 40 for said congeries 31 forms a cold air inlet chamber 41 at the bottom thereof, an intermediate chamber 42 containing said cellular structure and an upper outlet chamber 43 for the heated air. The fluid motor 45 is preferably mountedin said inlet chamber 41 with a fan 46 arranged to draw air into said outer casing through the stationary louvers 47 in the lower portion of said casing and force it through the passa eways 36 in said congeries of tubes, and out rom the heated air chamber 43 into the surrounding atmos here, through the foraminous panel or gri e 49.

Said fluid motor includes an outer casing 50 provided with ports 51 and 52 through which the heating fluid in the system circulates from the pipes 20 to the pipes 23. Said cas' 50 contains the rotor 54, the blade 55, anfie shaft 56 which latter is journaled in said casing-and in operative connection with said fan 46. Valves 57 and 58 may be pros vided localto' said motor casing to variably determine, by manual ad'ustment thereof, the

relative volume of the eating fluid which shall be directed to the radiator 21 and through the motor 45, It is to be understood that said valves ma be adjusted 'to vary and determine the spee and consequent air displacement effect of said fan 46 to attain the desired efiiciency of transfer of heat from the radiator to the surrounding atmosphere; it bein noted that such capacity should be increase and diminished in accordance with increase and decrease in the heat supplied to the radiator. Although said fan 46 is indicated as in coaxial relation with said shaft 56, it is to be understood that it may be connected therewith by gearing so as to be turned at a faster rate than said aft.

Although I find it convenient to employ a fluid motor of the rotary type indicated in Fig. IV; any other suitable type of motor may be em loyed. For instance, Fig. V shows a fluid motor 59 of the reciprocatory type. The fan 46 may be mounted directly upon the shaft 60 or, as shown, the fly wheel 61 may be connected by a belt 62 with a pulley 63 on the shaft 65 which carries a fan 46. Said motor 59 may be included in multiple relation with a radiator 21 in a bypass from the su ply pipe 20 to the exhaust return pipe 23 an be controlled by valves 57 and 58 as above described; but the fluid may be otherwise exhausted from said motor.

Therefore, I do not desire to limit myself to the precise details of construction, arrangement, or procedure herein set forth, as it is obvious that various modifications may be made there-in, without departing from the essential features of my invention, as defined in the appended claims.

I claim:

V 1. The combination with a radiator structure formin separate passagewa s for a heating fluid an air; of conduits for eating fluid of rotation of the motor leading to and from said radiator structure; means arran d to forcibly circulate air through the air passageways, including a rota an and a motor operatively connected wi said fan; means arranged to operate said motor by power from the heating fluid, including conduits leading to and from said fan motor and in multiple relation with said radiator conduits; and valve controlling means, respectively in said radiator and motor conduits arranged to variabl determine the relative volumes of heating uid respectively sup lied to said radiator and fan motor; where y all of the heating fluid utilized in operating said fan motor is returned into the radiator system to be reheated.

2. In heat exchange a paratus; the combination with a casing, having an air inlet. near the bottom thereof and an air outlet near the top thereof; of a cellular structure, in said casing, between said inlet and outlet, forming separate passageways for a heating fluid and air;vconduits for heating fluid leading to and from said cellular structure; means arranged to forcibly circulate air through said air passageways, including a rotary fan and a motor for the same in said casing between said air inlet and said ceilular structure; means arranged to operate said motor by power from the heating fluid, including conduits leading to and from said motor and in multiple relation with said radiator conduits; means arranged to jointly supply said heating fluid to said cellular structure and to said motor; and valve controlling means, respectively in said conduits connected with and cellular structure and with said motor, arranged to variably determine the relative volumes of heating fluid respective- 1y supplied to said cellular structure and to said motor; whereby the heat available in said cellular structure, and the speed of circulation of air with respect to said cellular structure, are adjustably variable.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this twenty-sixth day of November,

ARTHUR E.- PAIGE.
